We have 4 panels in our house. Two 200A main panels fed off of the same 600A meter base + one 80A sub panel fed from one of these main panels + one Time-Of-Use panel (car & boat chargers) fed from it’s own 200A meter base. Then we have a 200A panel in my studio (separate building) fed from the 600A meter base. This is US 240/120v split phase bonded neutral. We will have solar but probably not until fall (waiting on Tesla Glass to be available in MN). The meters are located on the studio building so from the 600A meter are two 100’ 200A feeds (4/0 IIRC) and one 10’ 200A feed to the studio panel.
Initially I just want to play w/ IotaWatt and make sure that it will do what I want (also considered TED & GEM but didn’t anything to justify the higher costs of those) and get an idea of what a number of specific loads are doing. If this goes well then I’ll expand for permanent monitoring.
If I initially have one base w/ CT’s on the two 200A main legs of one panel, what happens if I place circuit level CT’s on circuits on the other 200A panel? Will it measure them accurately? Or will I need to instead do one panel at a time? I assume aggregate info will be off in this scenario and that’s OK for now.
Long-Term I assume I’d need 5 bases - one for each panel/feed?
Will the AccuCT 200A x 25mm fit 3/0 OK if that is what we have? Suggestions for larger CT’s for the mains? (The markings are not visible on either panel so I’m waiting on our electrical contractor to let me know what these are.)
The AccuCT 50A are good up to 50A? I don’t need to downrate them any?
The panels are already tight. Are there 20A, 50A, 70A and 100A CT’s that are smaller (I’m fine w/ non-splits) that are recommended and reliable?
The panels are flush in a sheetrock wall. For now I’m just planning to stick the base on the wall w/ some 3M temp tape and run the feeds out between the panel box & cover. For Perm I assume I’ll need to mount a couple of J boxes w/ conduits in to the panels? Suggestions for this welcomed.
Thank you (and great forum here).
